Pepperl+Fuchs Sensor, an indispensable precision instrument in the industrial control industry

The P+F Pepperl+Fuchs sensor ultrasonic probe is mainly composed of piezoelectric wafers, which can transmit and receive ultrasonic waves. Low-power ultrasound probes are mostly used for detection. It has many different structures, which can be divided into straight probe, oblique probe, surface wave probe, double probe and so on. Ultrasonic sensing technology is applied in different aspects of production practice, and medical application is one of its most important applications. The following uses medicine as an example to illustrate the application of ultrasonic sensing technology. The application of ultrasound in medicine is mainly to diagnose diseases, and it has become an indispensable diagnostic method in clinical medicine.

The typical applications of P+F Pepperl+Fuchs sensors are non-destructive testing of metals and ultrasonic thickness measurement. In the past, many technologies were hindered by the inability to detect the inside of the object's tissues. The emergence of ultrasonic sensing technology has changed this situation. Of course, more ultrasonic sensors are fixedly installed on different devices to "quietly" detect the signals that people need. In future applications, ultrasound will be combined with information technology and new material technology, and more intelligent and highly sensitive ultrasonic sensors will appear. Ultrasonic waves have a great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. It can penetrate to a depth of tens of meters. When the ultrasonic wave hits the impurity or the interface, it will produce a significant reflection to form an echo, and it can produce a Doppler effect when it hits a moving object. The main materials of ultrasonic sensors are nickel-iron-aluminum alloy. Electrostrictive materials include lead zirconate titanate and the like. The ultrasonic sensor composed of piezoelectric crystal is a reversible sensor. It can convert electrical energy into mechanical oscillation to generate ultrasonic waves. At the same time, when it receives ultrasonic waves, it can also be converted into electrical energy, so it can be divided into transmitters or receivers. Therefore, ultrasonic testing is widely used in industry, national defense, biomedicine, etc.
